Rank 2 out of 10MountainBIKEBike-Helme im TestReleaseSeptember 2025

With its large helmet shell and soft padding, it sits extremely comfortably and without pressure points on almost all of the editorial team's heads. Adjusting the strap triangles requires a little effort, but they are also height-adjustable. Wears slightly sweatier than other AM/enduro helmets. The relatively short visor reduces the glare protection somewhat. Massive look, but not a heavyweight.
